63090499 ÷ 691 
The aim is to understand the frequency of 691 in 63090499.

Advancing to step 1:
When dividing 6 by 691, we get 0 with a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Include the next digit (3) from the dividend after 6, then repeat: 63 / 691

Step 2:
If we divide 63 by 691, we get 0 and a remainder of 63.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 63 to get 63.
Include the next digit (0) from the dividend after 63, then repeat: 630 / 691

Step 3:
691 can be fit into 630 0 times, resulting in a remainder of 630.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 630, we get 630.
Append the next digit (9) from the dividend to 630 and continue with: 6309 / 691

Step 4:
6309 divided by 691 is 9 with a remainder of 90.
The next digit of our result is 9. 
Result so far: 9.0
The remainder is 90 after subtracting 6219 from 6309.
Fetch the next digit (0) from the dividend, attach it to 90 and continue: 900 / 691

Moving on to step 5:
691 goes into 900 1 times with a remainder of 209.
Put 1 as the next digit of the answer. 
Result so far: 91.0
Subtract 691 from 900 to get 209.
Take the next digit (4) from the dividend and append it to 209, then repeat: 2094 / 691

On to step 6:
691 goes into 2094 3 times with a remainder of 21.
Record the quotient 3 as the next digit in the result. 
Result so far: 913.0
Deduct 2073 from 2094 and we're left with 21.
Bring next digit (9) of the dividend behind the 21 and repeat the process: 219 / 691

Let's proceed to step 7:
219 divided by 691 is 0 with a remainder of 219.
The next digit of our result is 0. 
Result so far: 9130.0
Subtracting 0 from 219 leaves us with 219.
Append the next digit (9) from the dividend to 219 and continue with: 2199 / 691

Let's proceed to step 8:
The number 691 fits into 2199 3 times, leaving a remainder of 126.
Put 3 as the next digit of the answer. 
Result so far: 91303.0
Subtracting 2073 from 2199 leaves us with 126.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1260, and continue the process.

Going ahead to step 9:
The number 691 fits into 1260 1 times, leaving a remainder of 569.
Record the quotient 1 as the next digit in the result. 
Result so far: 91303.1
Subtract 691 from 1260 to get 569.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5690, and continue the process.

Moving on to step 10:
If we divide 5690 by 691, we get 8 and a remainder of 162.
Put 8 as the next digit of the answer. 
Result so far: 91303.18
Deduct 5528 from 5690 and we're left with 162.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1620, and continue the process.

On to step 11:
691 can be fit into 1620 2 times, resulting in a remainder of 238.
Write down 2 as next digit of the result. 
Result so far: 91303.182
Deduct 1382 from 1620 and we're left with 238.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2380, and continue the process.

Let's proceed to step 12:
If we divide 2380 by 691, we get 3 and a remainder of 307.
The next digit of our result is 3. 
Result so far: 91303.1823
If we subtract 2073 from 2380, we get 307.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3070, and continue the process.

Going ahead to step 13:
3070 divided by 691 is 4 with a remainder of 306.
Write down 4 as next digit of the result. 
Result so far: 91303.18234
If we subtract 2764 from 3070, we get 306.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3060, and continue the process.

Step 14:
When dividing 3060 by 691, we get 4 with a remainder of 296.
Record the quotient 4 as the next digit in the result. 
Result so far: 91303.182344
Deduct 2764 from 3060 and we're left with 296.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2960, and continue the process.

Our division results in 91303.182344 with a remaining 2.96e-05.
